Deleted Redirects Still Working with themes plugins deactivated

In the output from the Apache server there are two attempts to redirect the URL. I solved the second attempt by disabling the URL Guess Function using the “Disable URL Autocorrect Guessing” plugin. So now https://www.trainingtutorial.com/autodesk-inventor-tutorials/inventor-2015-training is just being redirected to https://www.trainingtutorial.com/autodesk-inventor-training/inventor-2015-training, which produces a 404 page not found. Note the parent permalink “autodesk-inventor-tutorials” changed to “autodesk-inventor-training”, but the child permalink “inventor-2015-training” did not change. Since this redirect is not in the htaccess file the URL should not be redirected, which will also produce a 404 page not found. I tried adding a redirect to the htaccess file to the appropriate URL, but the page is still being redirected to the wrong URL above.

In addition to the link above redirecting without a redirect in the htaccess file I’ve found a new related problem. I’ve added a few 301 redirects back to the htaccess file and found they only redirect the post name (the first permalink in the redirect). The rest of the redirected URL is the same as the start redirect URL. So https://www.trainingtutorial.com/old post name/old child(s)/ is being redirected to https://www.trainingtutorial.com/new post name/old child(s)/ instead of https://www.trainingtutorial.com/new post name/new child(s). This is essentially the same problem with the link above except the link above is not in the htaccess file.
